Transition radiation is a fundamental process of light emission and occurs whenever a charged particle moves across an inhomogeneous region. One feature of transition radiation is that it can create light emission at arbitrary frequency…

Transition radiation is produced when a relativistic charged particle enters or leaves a solid medium. The electrons that produce synchrotron radiation may interact with the dust in circumstellar environments, leading to the emission of…
